---++ *Nevis Seminar*

The Nevis Seminar is designed to bring the different research groups at Nevis together to present their work on a monthly basis. Lunch will be provided 1/2 hour before the talks begin.

   * *Where*: Nevis Laboratories (directions: http://www.nevis.columbia.edu/directions.html), Mansion House Conference Room. Lunch will be in the dinning room in the mansion.
   * *When*: Usually the 4th Thursday of the month during Fall and Winter semesters.
   * *Schedule*:
*Winter* *2014:*
| Date | Time | Speaker | Title | Description | Notes | Slides |
| <p>Thursday Jan. 30th</p> | 1pm | Tim Andeen | The ATLAS Experiment, from Nevis to CERN | Columbia University has a large team of scientists working on the ATLAS experiment at the Large Hadron Collider (LHC) at CERN in Geneva, Switzerland. Scientists from Nevis have been involved in every aspect of the experiment. Significant components of ATLAS were developed and built at Nevis and work continues upgrading the detector. The latest searches for physics beyond the Standard Model will be discussed as we look forward to even higher energy collisions in 2015 and beyond. | Lunch at 12:30 pm | |
| Tuesday Feb. 18th | 1pm | Jose Alonso | Pushing the Envelope of Cyclotron Technology: from Medical Applications to Neutrino Sources | The Cyclotron, patented by E.O. Lawrence in 1934, has traditionally been a tool for nuclear physicists to study properties of nuclei. Even from the earliest days, however, applications of the beams from these machines in other fields have played an important role. Glenn Seaborg, in 1938 proposed the first use of an iodine isotope he discovered at the 27&rdquo; cyclotron as a medical tracer, and in that same year Ernest's brother John Lawrence developed a program of treating tumors with neutrons from cyclotron beams hitting beryllium targets. Today cyclotrons are in widespread use: for radioisotope production, for cancer therapy with proton beams, and for increasingly-diversified programs in nuclear and particle physics research. This talk will cover the range of applications, and the evolution of machines optimized for each, and will explore new developments, from compact superconducting machines tailored for medical uses, up to and including a new project for development of very high-current cyclotrons as compact, cost-effective neutrino sources. | Lunch at 12:30 pm | |
| Thursday Feb. 27th | 1pm | Mike Hahn | Evidence for Wave Heating in the Solar Corona | One of the major problems in astrophysics is to understand how the solar corona is heated to over a million degrees. In this talk I will review the coronal heating problem, its possible solutions, and present our results indicating that waves carry energy into the corona from lower layers of the Sun. | Lunch at 12:30 pm | |
| Thursday Mar. 27th | 1pm | André Loose | Counting krypton atoms, one at a time | Atom trap trace analysis (ATTA) is a method to detect trace amounts of noble gas isotopes, with up to one part per quadrillion sensitivity - equivalent to one drop of water diluted into a water cube as tall as the Empire State Building. I will talk talk about the ATTA setup at Columbia, which will be used to monitor the krypton contamination in the XENON1T dark matter detector. | Lunch at 12:30 pm | |
| Thursday Apr. 24th | 1pm | Rachel Carr | The Double Chooz Experiment | <br />The Double Chooz experiment, located in northeastern France, was designed to look for the oscillation of electron antineutrinos coming from nearby nuclear reactors. In 2011, it provided the first hint that this phenomenon exists, indicating that the neutrino mixing parameter theta_13 is nonzero. Since then, Double Chooz has developed many techniques to improve the precision of theta_13 measurements. I will talk about the experiment, our analyses, and what we've learned. | Lunch at 12:30 pm | |

*Fall* *2013:*
| Date | Time | Speaker | Title | Description | Notes | Slides |
| Sept. 26th | 1pm | | Laboratories tour | | Lunch at 12:30 pm | |
| Oct. 24th | 1pm | Ester Aliu | Astrophysics at the TeV scale | How experiments like VERITAS detect particles at this extreme energy and which scientific questions we try to address.The contribution of the Barnard and Columbia VERITAS groups will be described | Lunch at 12:30 pm | |
| Nov. 21st | 1pm | Joy Didier | EBEX: The E and B EXperiment. | Measuring the polarization of the Cosmic Microwave Background (CMB) provides us with a wealth of information on the origin, composition and dynamics of the universe. EBEX is a balloone-borne telescope designed to measure the polarization of the CMB. I will give an overview of the instrument and of the recent science flight in Antarctica. | Lunch at 12:30 pm | |
| Dec. 17th | 1pm | William Seligman | A Brief History of the Nevis Estate | + Christmas party | Lunch at 12:30 pm |  [[%ATTACHURL%/20131217-HistoryTalk.pdf][Slides]] |
